Transfer



Patented June 28, 1932 HELENA S. SADTLER, OF ERDENHEIM, PENNSYLVANIA TRANSFER No Drawing.

My invention relates to a transfer sheet for the marking or ornamentation of fabrics and more particularly to a novel and improved transfer sheet for transferring resists, pigments, dyes or discharges to fabrics and the like.

Gbjects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom to those skilled in the art, the same being realized through the means pointed out in the appended claims.

One of the objects of the present invention is the provision of a simple, inexpensive and easily used transfer sheet by which various markings or designs can be transferred to fabrics and the like in the home. A further object is the provision of a novel transfer by the use of which beautiful and useful resist effects can be simply and quickly produced. Still another object is the provision of a transfer for transferring resists to fabrics and simultaneously therewith transferring designs in other media to the fabric. Another object of the present invention is the provision of a novel transfer by which discharges, dyes or other coloring material can be transferred to fabrics and will be fast to boiling water and washing processes. A further object is the provision of a transfer for transferring colorless resists or colored resists and multicolored designs to fabrics whereby a manufacturer can more conveniently place resists and multicolored designs or marking on fabrics by transferring the designs than by direct printing on the fabrics.

In accordance with the present invention, the transfers preferably comprise a base of paper or the like, on which is deposited, in the form of a design,the transferable composition comprising a coagulable material, such as albumen, a softening material, such as glucose and/or glycerine, and, when it is desired to mark the fabric in addition to the resist, a marking medium which may comprise a discharge, a dye or a. pigment.

It will be understood that the foregoing general description and the following de tailed description as well are exemplary and explanatory of the invention but are not rerestricted thereon.

Application filed June 13, 1927. Serial No. 198,687.

Referring now in detail to the present preferred and illustrative embodiment, the transferable material, preferably comprises dried albumen, glucose, with or without the addition of glycerine. This compoistion is preferably made up as follows: the powdered, dried egg albumen is mixed with a suitable quantity of glucose, and, if desired, a small quantity of glycerine is added, and these ingredients are ground together in a paint mill, the proportions being adjusted to produce a smooth paste of the proper consistency for printing on paper or other base material.

Where it is desired to transfer only the resist, the transferable composition may be employed without further additions, but if a colored resist is desired, suitable pigments may be added to the ingredients before grinding. Among the pigments which are suitable are the following: line carbon black, Vermillion, chrome yellow, ultramarine blue, and insoluble lakes, such as a substantive dyestuif and mordant.

lVhere it is desired to transfer a dye to the fabric with the resist, direct dyes are incorporated in the paste and are ground therewith until smooth and uniformly distributed. With such transfers, the albumen serves as a mechanical binder to hold the dye on the fabric until the fabric is further treated.

lVhere transfers are desired to transfer discharges to a colored fabric to be decorated or marked, a reducing agent, such as anthraquinone in combination with zinc dust and bisulfite of soda, is incorporated in the transferable composition, and, if desired, vat dyes may also be added to the otherwise colorless composition.

The transfer sheets employing the compositions set forth above may be produced by printing from relief or intaglio plates or cylinders inked with the desired transferable composition. 95

T0 facilitate the transferring operation and to insure the maintenance of contact between the transfer and the fabric to be decorated, the transfer sheets, immediately after printing and while the printed impressions are still moist are dusted with a colloidal gum, such as powdered gum tragacanth. Gum tragacanth is insoluble in cold water but is soluble in hot water and enables the trans ferring to be easily effected by merely wetting the fabric and pressing the transfer into contact therewith, where it is allowed to remain for several minutes or until the trans ferable design is transferred.

After the transferable design has been transferred, the fabric may be immersed in boiling water or subjected to moist heat to coagulate the albumen and to set the dye or to activate the discharge.

In cases where the fabric to be decorated is one which would be injured by the application of hot or boiling water, a coagulant may be employed, and for this purpose a small amount of paraformaldehyde may be incorporated in the transferable composition or the fabric, to which the design has been transferred may be immersed in a 5% solution of formaldehyde.

The invention in its broader aspects is not limited to the specific compositions described but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the invention and without sacrificing its chief advantages.

I claim:

1. A transfer sheet for transferring designs to fabrics, said sheet having a marking thereon of a composition including a coagulable protein and glucose.

2. A transfer sheet for transferring designs to fabrics, said sheet having a marking thereonvof a composition including a coagulable protein, a dyestuif and a colloidal gum insoluble in cold water but soluble in hot water.

3. A transfer sheet for transferring designs to fabrics, said sheet having a marking thereon of a composition including albumen, glucose and a coagulant.

4. A transfer sheet for transferring designs to fabrics, said sheet having a marking thereon of a composition including albumen, glucose and a dyestuif.

5. A transfer sheet for transferring designs to fabrics, said sheet having a marking thereon of a composition including albumen, glu cose and a reducing agent.

6. A transfer sheet for transferring designs to fabrics, said sheet having a marking there on of a composition including albumen, glucose, glycerin, a coagulant and a reducing agent.

7. A transfer sheet for transferring designs to fabrics, said sheet having a marking thereon of a composition including a coagulable protein, glycerin, a vat dyestuif, and a reducing agent.

8. A transfer sheet for transferring designs to fabrics, said sheet having a marking thereon of a composition including a coagulable portein, glucose, glycerin, paraformaldehyde and a reducing agent.

9. A transfer sheet for transferring designs to fabrics, said sheet having a marking thereon of a composition including a coagulable protein, glucose, a coagulant, a colloidal gum insoluble in cold water but soluble in hot water, a vat dyestutl', and a reducing agent.

10. A transfer sheet for transferring designs to fabrics, said sheet having a marking thereon of a composition including albumen, glucose, a vat dyestuif and a reducing agent.

11. A transfer sheet for transferring designs to fabrics, said sheet having a marking thereon of a composition including albumen, paraformaldehyde, a dyestuif and a colloidal gum insoluble in cold water but soluble in hot water.

In testimony whereof, I have hereunto signed my name, at Philadelphia, in the State of Pennsylvania, this sixth day of June, 1927.
